Fix attributes of CueSheet object being included as tags in track files (gh-23)

• Fix attributes of CueSheet object being included as tags in track files

• Update VERSION

fix(albuminfo): Catch exceptions when trying the part cue sheet (gh-18) (#22)

• Catch problems with detecting / decoding character encoding of cue sheet file
• Catch parsing errors
• refactor fix provided for gh-19 to also fix a problem with albums without tags

Fix case when folder ends with .flac|.wav pattern. (#21)

feat(albuminfo): Allow cuesheets with full name of album file (gh-15) (#17)

When scanning for accompanying cueshees for an album file "album.flac"
trackfs checks for cuesheets files with four possible names:

• album.cue
• album.CUE
• album.flac.cue
• album.flac.CUE

feat(fusepath): Make album extension matching by default case insensitive (gh-13) (#16)

Now recognizes '.flac' as well as '.FLAC' or even '.fLaC' as valid extension.
Bahaviour can still be modified via --extension parameter
Virtual track files will still only use the lower-case variant '.flac'

This is a bugfix for gh-12

feat(trackfs): Support WAVE files with accompanying cue-sheets (gh-8) (#11)

To introduce WAVE support a few breaking changes got introduced:

• New naming scheme for virtual files; in case you have indexed the virtual
  filesystem in some media-server you have to re-index it
• parameter keep-flac-cue got renamed to keep-album
• parameter extension now has to be a regular expression
• trackfs now also uses album meta-data from the cue-sheet to backfill
  missing entries in the album file
• basic support for album-art in accompanying jpg files

• fix(flacinfo): escape tags for flac arguments

Special characters in tags, esp. title can cause invalid flac parameters when extracting a trackfs/cuesheet.
refactor(cuesheet): Major refactoring of cuesheet parser and support for album metadata.

• feat(albuminfo): backfill missing album tags from cuesheet

Renamed flacinfo to albmuminfo to perpare pending wav support.
Use cuesheet albuminfo in case flac file has not album metadata.

In case the flac file doesn't have an embedded cue-sheet, trackfs scans the directory for a file with the same basename and ".cue"-extension and reads it as cue-sheet.

Additional additions

• return accurate file size for track when already extracted in cache
• bugfix for concurrent reads
